Giving Up Intro Tab

This melody is repeated throughout the song, primarily featured in the intro and the post choruses.
 
In the studio version of the song, they pitch the song down slightly. I'd estimate something like a quarter
step down from standard. So playing along to the official version is quite tricky. Though live version seem
to stay in this key pretty consistently.
